摘要 将LiMn2O4和LiCoO2在强力混合机中混合均匀,获得均匀的共混正极材料。通过电化学测试研究了LiMn2O4/LiCoO2两种电极材料混合比例对锂离子电池循环性能的影响,并比较了LiMn2O4与LiCoO2混合前后在常温和高温环境下循环性能的差异。实验结果表明:在LiMn2O4与LiCoO2共混后制得的锂离子电池在常温和高温环境下都具有良好的循环性能。 The LiMn2O4 and LiCoO2 material were blended in a powerful agitator.The effects of blending ratio on the cyclic performance of Li-ion batteries were investigated by means of electrochemical measurements.The differences of the cyclic performance of pure LiCoO2,LiMn2O4,and LiMn2O4 blended LiCoO2 materials at room and high temperatures were also compared.The experimental results showed that the cyclic performance of Li-ion battery used LiMn2O4 blinded LiCoO2 as cathode material was good at ambient and high temperatures.
